Carbon Gold BioChar Tree Soil Improver 4L from Harrod Horticultural New

A study by the company’s research labs on 2,000 established ash trees over three years in Essex found that while a third of the established trees monitored have become infected with Chalara Ash dieback, none of the 20 trees which had enriched biochar applied to their roots were hit.

Ideal for decompacting and amending waterlogged soils, and stabilising soil moisture in sandy soils, enriched biochar allows trees to grow strong, healthy root systems in the harshest conditions.

Carbon Gold’s peat free biochar products are used by professional growers, allotments and home gardeners because they deliver superb results.

Bio Char is enriched with mycorrhizal fungi, seaweed and wormcasts. For trees, shrubs, roses, bare root stock and hedging.

Supplier recommends 1kg of GroChar BioChar Tree Soil Improver per m2 under the canopy of the tree which is half of 4L box.

Ideally it needs to be forked into the ground and covered with a mulch otherwise the natural biology will react to the sunlight
